I tried this on DMD64 v2.059 on linux (openSUSE).

Static initialization of a static-sized array within a union seems to 
assign only the first entry of the array. If the array is taken out of 
the union and the union is removed, then the initialization works fine.

struct Klass
{
    union {
        double[3] vals = void;
        struct { double x, y, z; }
    }
}

void main()
{
    Klass v = {[1,2,3]};

    import std.stdio;
    writeln(v.vals); // outputs [1, nan, nan]; expected [1, 2, 3]
}
